All questions of Digit Sum Method for Class 6 Exam

To find the digital sum of a number, we need to add up all the digits in the number. In this case, we have the number 124.

Step 1: Break down the number into its individual digits.
The number 124 can be broken down into three digits: 1, 2, and 4.

Step 2: Add up the digits.
Now, we add up these three digits: 1 + 2 + 4 = 7.

Therefore, the digital sum of the number 124 is 7.

Explanation:
The digital sum of a number is the sum of all its digits. In this case, we have the number 124. To find the digital sum, we break down the number into its individual digits, which are 1, 2, and 4. Then, we add up these digits: 1 + 2 + 4 = 7. Therefore, the digital sum of the number 124 is 7.

To solve the equation 1930 + 6196, we can simply add the two numbers together.

1930 + 6196 = 8126

Therefore, the answer to the equation is 8126.

Now, let's verify the answer using the Digital Sum method.

The Digital Sum method involves finding the sum of the digits of each number, and then adding those sums together. If the digital sum of the result matches the digital sum of the equation, then the answer is correct.

Step 1: Find the digital sum of 1930
Digital sum of 1930 = 1 + 9 + 3 + 0 = 13

Step 2: Find the digital sum of 6196
Digital sum of 6196 = 6 + 1 + 9 + 6 = 22

Step 3: Find the digital sum of the result (8126)
Digital sum of 8126 = 8 + 1 + 2 + 6 = 17

Step 4: Compare the digital sum of the result (17) with the digital sum of the equation (13 + 22 = 35)

Since the digital sum of the result (17) does not match the digital sum of the equation (35), the answer 8126 is incorrect.

Therefore, the correct answer is not any of the given options.

Digital sum refers to the sum of all the individual digits in a number. In this case, we need to find the digital sum of the number 339.

To find the digital sum, we will add the individual digits of the number together.

Solution:
Step 1: Break down the number into its individual digits.
The number 339 can be broken down into the digits 3, 3, and 9.

Step 2: Add the individual digits together.
3 + 3 + 9 = 15

Therefore, the digital sum of the number 339 is 15.

Hence, the correct answer is option 'A', 15.

Summary:
- The number 339 is broken down into its individual digits: 3, 3, and 9.
- The individual digits are added together: 3 + 3 + 9 = 15.
- Therefore, the digital sum of the number 339 is 15.

Adding the Numbers:
First, we need to add the numbers 9670 and 398 together to find the sum.
9670
+ 398
------
10068

Verifying with Digital Sum Method:
To verify the answer using the Digital Sum method, we need to find the digital sum of both the sum obtained and the correct answer.

Finding Digital Sum of 10068:
1 + 0 + 0 + 6 + 8 = 15
1 + 5 = 6

Finding Digital Sum of 10088 (Correct Answer):
1 + 0 + 0 + 8 + 8 = 17
1 + 7 = 8
Since the digital sum of the correct answer 10088 matches the digital sum of the sum we calculated (10068), we can confirm that the correct answer is indeed 10088.
